These are the special properties of nitinol that you should know:
1. Shape Memory Function
Nitinol is deformed by an external force at a certain temperature. After the external force is removed, the deformed shape can still be maintained, but it can automatically return to its original shape at higher temperatures.
2. Superelasticity
nickel-titanium alloy with very good superelastic property,when deformed, it will bounches back, this property make it a great material
for many fields, like gliders, fishing etc.
3. Corrosion Resistance
According to the studies,the corrosion resistance of nickel-titanium alloy is better than the best medical stainless steel, so it is widely used in the medical field.
4. Biocompatibility
The titanium dioxide on the surface of the nickel-titanium alloy acts as a barrier, which can inhibit the release of nickel and make the nickel-titanium alloy with good biocompatibility.
5. Good Shock Absorption
The initial vibration amplitude of super-elastic nitinol wire is only half of that of stainless steel wire.
